First make a fork of this repository. Make sure you are on your fork rather than still on this page, and then clone the repository to your local computer.
I suggest giving your pair collaboration rights rather than making a separate fork for them. If you prefer making a separate fork to share your work, wait until you have completed the exercises and pushed your code back to the fork to do so!
Go to the prime lists directory for instructions. I suggest viewing it on GitHub rather than opening it locally (the formattting looks better on GitHub).
Start with the range exercise and then move on to the for loop exercise.
